Your pulse rate is the number of times your heart beats per minute12.A "normal" pulse rate depends on your age and current level of fitness2.The average resting heart rate for most adults, including senior citizens, is between 60 and 100 beats per minute1.Young children tend to have high...
Age: Gender: Female Male CalculateWhat is a good HRV while sleeping? In general, heart rate is low and heart rate variability is high during nighttime. During sleep, the parasympathetic nervous system activity dominates, lowering heart rate, body temperature, and relaxing muscles. Our heart rate...
Heart rateAttentionMental retardationReaction timeTime estimationThe relationship between heart rate (HR) changes and fixed reaction time (RT) performance was studied in groups of normal and mentally retarded male Ss. Each 5 received blocks of 15 RT trials during 4-, 7-, and 13-sec preparatory ...
Age distribution, body size and heart rate were equal between genders. Only 12/141 children were younger than 6 years [45]. Boys had larger ventricles than girls [45]. LVEF was found to be slightly higher in boys (67% vs 65%; p 0.01), but not for the RV [45]. Gender differences ...
This study analyzed Heart Rate Variability in a large sample of active young subjects within a narrow age range (18 to 25), using time and frequency domain methods and a Poincaré plot. Heart rate was recorded (beat to beat) for 30 minutes at rest in 200 healthy subjects divided into 4 ...

Normal Heart Rate A healthy heart rate for adults over 18 is usually between 60 and 100 beats per minute (bpm). Your number may vary. The best time to measure your resting heart rate is just after you wake up in the morning before you start moving around or have any caffeine. ...

What's the normal heart rate for an active adult? I have a normal resting heart rate (it's usually around 80), but when I am active (walking up stairs or jogging), I feel like my heart rate goes up a lot. I can actually hear my heart pounding. It scares me. ...
The within-subject variation was ±0.044 for the tachycardia ratio and ±0.18 for the Valsalva ratio, while the between-subject variation was 0.10 for the tachycardia ratio and 0.37 for the Valsalva ratio. The heart rate response to the Valsalva manoeuvre was also found to be reproducible in 7...
